Completeness of Cytoreduction (CC) score of Sugarbaker: largest residual tumor nodule after cytoreductive surgery.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Largest residual tumor nodule (mm)
- 2
Result: CC-1.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Grade
- largest residual nodule: CC-0 = none, CC-1 = <2.5 mm, CC-2 = 2.5 mm to 2.5 cm, CC-3 = >2.5 cm or confluence.
- Complete
- CC-0 and CC-1 are a complete cytoreduction (nodules <2.5 mm are within intraperitoneal-chemo penetration depth); CC-2 and CC-3 are incomplete.
What you enter
- Largest residual tumor nodule (mm): 0 = CC-0, <2.5 = CC-1, 2.5-25 = CC-2, >25 = CC-3
- Confluence of unresectable disease (forces CC-3)
